Chimeric Antigen Receptors to ALK for Treating Neuroblastoma and Other Solid Tumors

Description of Technology: Chimeric antigen receptors (CARs) are hybrid proteins consisting of an antibody binding fragment fused to protein signaling domains that cause T-cells which express the CAR to become cytotoxic. Once activated, these cytotoxic T-cells can selectively eliminate the cells which they recognize via the antibody binding fragment of the CAR. By engineering a T-cell to express a CAR that is specific for a certain cell surface protein, it is possible to selectively target those cells for destruction. This is a promising new therapeutic approach known as adoptive cell therapy.

Anaplastic lymphoma kinase (ALK, CD246) is a tumor-associated antigen that is expressed on the cell surface of pediatric neuroblastomas and some non-small cell lung carcinomas (NSCLC). This technology concerns the development of four (4) CARs, each comprising a different antibody binding fragment to ALK. The CARs, known individually as ALKCAR15, ALKCAR48, ALKCAR53 and ALKCAR58, can be used in adoptive cell therapy treatment for neuroblastoma and other solid tumors which overexpress ALK or variants thereof.

Potential Commercial Applications:

Treatment of cancers associated with expression of ALK or variants thereof.

Specific cancers include neuroblastoma, NSCLC and other solid tumors.

Competitive Advantages:

High affinity of the ALKCAR15, ALKCAR48, ALKCAR53 and ALKCAR58 increases the likelihood of successful targeting.

Description of Technology: Ty21a, the licensed oral live, attenuated bacterial vaccine for Salmonella typhi (the causative agent of typhoid fever), has been engineered to stably express a variety of target LPS (lipopolysaccharides) and protein antigens to protect against shigellosis, anthrax, and plague. Ty21a induces mucosal, humoral, and cellular immunity and can be utilized as a multivalent vaccine vector that is inexpensive to produce. Salmonella species encode inducible acid tolerance, but this genus does not survive well below pH 4. Shigella and enterohemorrhagic E. coli isolates have more effective acid resistance systems than Salmonella and can survive an extreme acid challenge of pH 1-2 (the acidity of the human stomach when full).

This application claims an engineered Ty21a vector that can survive a very low pH for two to three hours (i.e.. normal transit time through a full stomach), allowing for a final delivery format for Ty21a as a rapidly dissolvable wafer, instead of the large bullet-size enteric-coated capsule, which small children cannot swallow. This formulation enhances the ability of the immunogenic composition and/or vaccine to stimulate immune responses sublingually and throughout the intestinal tract.

Collaborative Research Opportunity: The Food and Drug Administration, Center for Biologics Evaluation and Research, is seeking statements of capability or interest from parties Start Printed Page 78371interested in collaborative research to further develop, evaluate or commercialize acid-resistant Shigellosis vaccines.

Assay to Screen Anti-metastatic Drugs

Description of Technology: Scientists at the NIH have developed a research tool, a murine cell line model (JygMC(A)) with a reporter construct, of spontaneous metastatic mammary carcinoma that resembles the human breast cancer metastatic process in a triple negative mammary tumor. The assay is useful for screening compounds that specifically inhibit pathways involved in mammary carcinoma and can improve clinical management of triple negative breast cancer which are greatly refractory to conventional chemo and radiotherapy. The key feature of the cell line is that when introduced orthotopically into the mammary gland of immunocompromised mice it produces murine mammary tumors that rapidly metastasize to distant sites, such as lungs, lymph nodes, liver and kidneys. This allows for precise tracking of tumor growth and metastasis.

Potential Commercial Applications:

Laboratory tool to investigate molecular mechanisms and/or signaling pathways involved in tumorigenesis, angiogenesis and metastasis of breast cancer and its response to therapy (in vivo and in vitro).

Collaborative Research Opportunity: The National Cancer Institute is seeking statements of capability or interest from parties interested in collaborative research to further develop, evaluate or commercialize mechanism of tumor growth and lung metastasis.

Mouse Model for the Preclinical Study of Metastatic Disease

Description of Technology: The successful development of new cancer therapeutics requires reliable preclinical data that are obtained from mouse models for cancer. Human tumor xenografts, which require transplantation of human tumor cells into an immune compromised mouse, represent the current standard mouse model for cancer. Since the immune system plays an important role in tumor growth, progression and metastasis, the current standard mouse model is not ideal for accurate prediction of therapeutic effectiveness in patients. This may contribute to increased failure in later phases of clinical trials, as appropriate tumor-host interactions are not preserved.

This technology establishes a system for producing mouse cancer models where the model is not immune compromised, providing an environment which is more akin to the disease state of cancer patients. To establish the model, a tumor is (a) developed in tissue that has been propagated by serial transplantation (rather than cell culture), (b) labeled (using lentiviral vectors) with bioimaging markers (e.g., green fluorescent protein (GFP) and luciferase), and (c) transplanted into immunocompetent mice. Once established, the model can be used to monitor tumor growth, progression and metastasis through standard imaging techniques. The effectiveness of a given therapeutic approach can also be monitored using the same techniques.

Collaborative Research Opportunity: The National Cancer Institute is seeking statements of capability or interest from parties interested in collaborative research to further develop, evaluate or commercialize preclinical models allowing consistent disease tracking in normal immune context.

Hexanucleotide Repeat in the C9orf72 Gene for the Diagnosis and Treatment of Amyotrophic Lateral Sclerosis and Frontotemporal Dementia

Description of Technology: This invention relates to the discovery of a pathogenic GGCCCC hexanucleotide repeat expansion in the first intron of the C9orf72 gene on chromosome 9p21 in patients exhibiting amyotrophic lateral sclerosis (ALS) and/or frontotemporal dementia (FTD). The inventors have previously identified a strong association signal in this genomic region and used this information to identify the underlying pathogenic mutation. The pathogenic repeat expansion accounts for up to 50% of familial ALS and familial FTD cases and up to 10% of sporadic ALS and sporadic FTD cases in European ancestry populations. The inventors represent that this finding will be the basis of diagnostic screening for ALS and/or FTD patients, as well as an important target in the development of therapeutics for ALS and/or FTD.
